LS1 AND twin turbos! Now we're talkin'

Featured Replies

I thought you guys might be interested in the engine that one of the tuners I know on an Australian forum has built for his street/strip car.

The engine isn't run in yet, so the revs have been limited to 4500 and the boost is currently capped at 10 psi, but even with those restrictions it's producing 455 rwhp at 4500rpm running through a T56 6 speed.

Once its run in, he'll be winding up the boost and the revs. He's aiming for 700 rwhp on pump fuel and 10 second 1/4 mile times.

GM should bring those pickup cars over to the states. I wonder how much they tow? Imagine one with that up coming GM diesel that will go into the CTS.

There's still some work to be done on the timing, mixture, and exhaust ...
